Abstract

The utility model discloses a lid unscrewing device and is characterized in that the device is a ring in the same size with the lid; the ring inside is provided with the saw teeth corresponding to the figure outside the bottle lid; and the outside of the lid unscrewing device is a polygon with grooves. In the use, the unscrewing device is positioned onto the bottle lid and gripped with hand. Then the saw teeth will chuck the figure of the bottle lid. Finally, rotation is conducted with force to open the bottle lid.

Description

Cap screwing device

Technical field

The utility model relates to the bottle cap technical field, concrete relates to a kind of cap screwing device of opening bottle cap.

Background technology

Summer, people often had a drink, but tighter when bottle cap, when perhaps more wet and slippery on hand, needed very big strength that bottle cap is opened, and perhaps were difficult to bottle cap is opened.

The utility model content

The purpose of this utility model is to provide a kind of cap screwing device that is easy to twist-off closure.

In order to achieve the above object, the technical solution of the utility model is such, a kind of cap screwing device, it is characterized in that, described cap screwing device is an annular that conforms to the bottle cap size, described ring-shaped inner part has with bottle cap outside texture wants the sawtooth that meets, and the described cap screwing device outside is the polygon of a band groove.

During use, cap screwing device is enclosed within on the bottle cap, holds with hand-tight, sawtooth will stick the texture of bottle cap, and firmly rotation can be opened bottle cap again.

Beneficial effect because cap screwing device inside has screw thread, is easy to bottle cap is opened after blocking bottle cap, and greatly facilitate people and open bottle cap, and also simple in structure, volume is little, is easy to carry about with one.

Description of drawings

Describe the utility model in detail below in conjunction with the drawings and specific embodiments;

Fig. 1 is the structural representation of a kind of cap screwing device of the utility model;

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.

A kind of cap screwing device is characterized in that, described cap screwing device 1 is an annular 2 that conforms to the bottle cap size, and described annular 2 inside have the sawtooth 3 that is consistent with bottle cap outside texture, and the described cap screwing device outside is the polygon 4 of a band groove.

During use, cap screwing device 1 is enclosed within on the bottle cap, holds with hand-tight, sawtooth 3 will stick the texture of bottle cap, and firmly rotation can be opened bottle cap again.

Although the foregoing description is described the utility model, for the technical personnel of the industry, still can do multiple variation to present embodiment, therefore, every employing similar variation of the present utility model all should be listed protection domain of the present utility model in.
